    Rolls SX45 reviews

    SX45 Stereo Crossover is rated 4.4 out of 5 by 5.
    Rated 5 out of 5 by from Just the ticket! I bought the Rolls SX45 to separate my avr preamp output prior to bi-amping my speakers. That worked fine and I highly recommend it for anyone bi-amping on a budget.I had not intended to use the High Pass and Low Pass adjustments but have found them very useful and now just plug the phono pre-amp or DAC straight into SX45 and use it for volume adjustment when listening to music.I do not use a subwoofer so cannot comment on those outputs.My only gripe is not having a power button on the box - unplugging mains supply is a pest.

    Rated 5 out of 5 by from Don't leave home without one The Rolls SX45 crossover is a must have unit for domestic and pro instalations. This unit will plug into your audio equipment and allow you to dial up and tailor a perfect crossover point and output levels. There is also a mono output for use with a single subwoofer. You can even use it in a good car hifi setup. Great Rolls sound using discreate electronics, damped level controls and metal enclosure. A quality product that will solve those sub sat problems at a tiny price. Keep one in your kit.

    Rated 4 out of 5 by from Great, simple design and clean sound. I bought this to use on gigs for my portable organ. I play a lot of left hand bass lines and finding one amp the covers the organ's frequency range is difficult without hauling a full-size leslie. So the idea is two amps with the crossover splitting them. I have not used it in this application yet but it should work fine. I have been using it for my home stereo. Its nice to supplement a small pair of desk speakers with some real bass on the floor and this can essentially turn any sizable speaker into a subwoofer. It works great. I would have given it five stars except that the volume control for the low level only works on the stereo low outs and not on the mono low out. If i want more out of the low speaker I just turn down the highs and raise the input volume knob. Also, there is no on/off switch. Its just on once plugged in.

    Rated 4 out of 5 by from Great cheap and effective bi-amp solution I'm using the ROLLS SX45 to split output from my pre-amp into mid/high, which then feeds back into my main power amp and runs some bookshelf speakers, and low, which I feed directly to my powered sub-woofer. Setup was super simple, I just needed some extra RCAs. Resulting sound now is super clear, crisp and with punchy bass. I can alter the cross-over point easily to suit the music I'm listening to and I'm also able to turn up the highs or lows, depending on if I want to annoy the neighbours with booming bass, or keep it quiet late at night. For Australian users - the powerpack supplied can easily be converted to fit AU power sockets by bending the pins with a pair of pliers (it's rated at 110-240v so no issue with voltage). My only gripe is that there is no power switch, so you need unplug it or switch off at power point. I've gotten around this by putting all of my stereo components on one power-board (pre-amp, power-amp, sub, crossover, turntable) and I can switch it all on/off at the wall. Easy.

    Rated 4 out of 5 by from Great Compact Crossover This is a great, small, two channel crossover that I needed to split out the signal coming from my laptop to send the separate high and low inputs into my receiver and out to satellite and sub speakers. The frequency threshold and input/output level options are great!
